A potentially violent storm moving slowly off of the Northern California coast is expected to slam into Los Angeles and Orange counties and the Inland Empire on Friday afternoon, bringing 60 mph winds and heavy rains that could cause flooding, according to the National Weather Service.

The storm was also expected to bring 3 to 5 inches of rain to Los Angeles County, and 2 to 4 inches to Orange County and the Inland Empire.

Mud slides and urban flooding are possible throughout the region.

Coastal areas will also be impacted, with waves possibly reaching up to 9 feet on Friday. Saturday, waves could reach 15 feet in some areas such as Huntington Beach.
